l Application filed December 28, 1915. Serial No. 69,039.

A following is a specification.

In the operation of an ordinary laundry i gas stove, the products ofcombustion of the gas are discharged into the room and even Where theburner is close to the bottom of the boiler a poisonous gas is generatedand inhaled by the person in the room, often with fatal results.

The object of my invention is to provide means in connection with a gasburner for supporting the boiler and conducting away the products ofcombustion and poisonous gases, and at the same time taking away thesteam from the boiler. which is ordinarily discharged into the room andcondenses on the; Hoor or walls` Other objects of the invention willappear from the following detailed description.

The invention consists generallyT in various constructions andcombinations, all as hereinafter described and. particularly pointed outin the claims.

In the accompanying drawings-forming part of this specification, Figure1 is a vertical sectional view through a heater and boiler embodying myinvention, Fig. 2 is a sectional view on the line mof Fig. 1 Fig. 3 is adetail sectional view, showing the manner of supporting the boiler atthe top of the heater.

In the drawing,.2 represents the shell or jacket of the heater, madepreferably of sheet metal, and supported upon suitable legs 3. Brackets4 are secured to said legs and support the plate 5, having a series-ofair intake openings G therein. beneath a gas burner 7. This burnercommunicates through the jacket 2 with a gas supply pipe 8 and a nozzle9 is mounted on 'an extension of the pipe 8 and arranged to project aflame through a port 10 in the wall. of the jacket for the purpose ofigniting the gas in the main burner, the flow of gas to the burner andnozzle being controlled by valves 11 and 12.

At the top of the jacket a support for the boiler is provided,consisting, preferably, of i an angle bar bent to a circular form andhaving a horizontal flange 13 projecting into the opening in the top o11the jacket and its vertical fiange secured to the side walls of Athejacket. An elbow 14 is provided at the top of the jacket on one side anda pipe 15 communicates therewith and forms a vent;

:for the products: of combustionv of the burner, vand for any gaseswhichinay be generated under the boiler.

16 represents a boiler, preferably cylindrical in forni a-iid having acover 17 and an outwardly rolled bead 18 at its .upper edge that isadapted to rest on the horizontal flange 13 and support the boilerwithin the jacket. Handles 19 are preferablyslecured to the walls of theboiler and lit within notches'20 in the flange 13. I prefer also toprovide openings 21 in theupper walls of the boiler through which thesteam from the boiling clothes'n'ay escape into'the` jacket.

The. passage of the products of combustion around the boiler and throughthe vent pipe will create or establish a circulation and cause thesteam/flowing out through the openings 21 to immediately pass to thevent pipe, mingling with the products of combustion therein. In this wayI not only avoid the diffusion of the products ot' combustion andpoisonous gases/from the flame of the burner, but also-remove the steamof the boiling clothes, which usually is discharged into the room andcondeiises on the walls or any articles that may be in the room. I thusnot only eliminate entirely the dangerous gases produced at the burner,but also dispose of the steam which may come from the boiling clothes orwhatever may be contained in the boiler. Such a device may, of course,be used in connectionwith a cooking utensil and still be within thescope of my invention. l

' Near the bottom of the boiler I prefer to provide a guard 22 bolted tothe jacket and having an inwardly and downwardly extending flange 23which terminates near the wall of the boiler and is adapted to directthe gas Hames downwardly and forwardly to a gap or opening that isprovided between the ends of the guard. This guard compels y theproducts of combustion to follow a circuitous pathiii the jacket andlinsures the exposure of all ortions of the boiler wall to the action othe burner Aflame. This deector or guard 22 may be varied in length,according to the size of the passage desired for the products ofcombust' n.

BEST AVAlLABLE COP` The device may be ,made in various sizes and invarious ways the details of construction herein shown and described maybe modified aid still be Within the scope of my invention.

I claim as my invention:

l. The combination, with a sheet metal jacket having an open top andclosed bottorn, of a gas burner mounted on said bottoni, said jackethaving a flange encircling its open top and provided near said flangewith an exhaust opening, a pipe connection therefor, a boiler fittingwithin said jacket and seated on said flange and forming a substantiallysteam-tight joint therewith7 the wall ot' said boiler having openingstherein contiguous to said exhaust opening, for the purpose specified.

The combination. with a jacket having 3. The combination, with` a jacketund a burner mounted therein, of a boiler suspended within said jacketand spaced from said burner and the walls of the jacket, a delectordevice inter osed between said boiler and the walls o said jacket and extending artially around the boiler, compelling t 1e flames and productsof combustion from the burner to follow a tortuous path around saidboiler,a vent pipe leading from saidfjacket, said boiler havingdischarge openings for the passage of steam to said vent pipe. f

4. The combination, with a jacket and a burner mounted therein, of aboiler fitting within the open top of said jacket and depending to apoint adjacent said burner, the upper walls of said jacket having anexhaust opening and a pipev connection therefor, the walls of' saidboiler havmg openings therein to allow the esca of steam into the spacebetween said 011er and jacket, said jacket having means above saidburner between it and said exhaust opening:r Jfor deflecting the laniesfrom said burner and' compelling them to follow a tortuous path aroundsaid boiler.

In witness whereof, I have hereunto set my hand this 23d day ofDecember, 1915.

JOHN T. LUCAS.
